Just a little pain and a little worry

Rae
So here we go. Long story short I was on some sort of birth control for almost 6 years straight because my cramps were horrendous. Feb 2016 I stopped taking it and my periods became mostly normal give or take 3 days and my cramps were manageable. Fast forward November 2016 I meet the man I'm with now and I'm so in love, as of Feb we were like hey I wonder if I can get pregnant so we weren't really trying but also weren't using condoms. I haven't missed a period, I haven't been late and nothing weird ever happened. Well my period is due in roughly 7 days but today I started cramping like I do on the first day of my period so I freaked out and went to go check to see if she was early and nope no blood. So I'm confused as to what this could be. In Feb of 2015 I was told I have an ovarian cyst but nothing major and never had anything wrong with that. I guess my question is ladies has this ever happened to you and what, if anything did doctors tell you or that you found out. Thank you ❤
